Terraria: how to set up multiplayer to play in LAN with friends

This guide will show how to set up a game for multiplayer via LAN. With Steam version or overwise.

General setup

To be able to play with friends you need to connect your computers in LAN with software like Radmin VPN

And you all need to be in the same network - gaming or private

Make sure everybody has the same game version

You need to access Terraria Server file. There are two ways of doing it:

if you have Steam version. In Steam go to Terraria -> Properties -> Tab Local files -> Browse local files. Local folder with all Terraria files should be opened. There you need to find file "start-server.bat" you need to double click on it
if don't have Steam version. Right-click on the game icon on the desktop and Choose "Open file location". Local folder with all Terraria files should be opened. There you need to find the "TerrariaServer" file. Double click on it to launch.

After you've launched the file black command window will be opened

type in 3 to create Builder's workshop or type "n" to create a New World then press Enter (depending on the game version list can be different, so please read all the instruction from the program carefully)
type in number of players, maximum is 16, press Enter
server port by default is 7777, just press Enter again
automatically port forward? type in "y" and press Enter
next you can setup server password or leave it blank. If you choose to have a password you need to share it with your teammates
Press enter and you should see several progress report running in the window. In he end it should say - "Server started"

Now on to the game itself!

Open Terraria, click on Play in the main menu -> Multiplayer -> Join via IP (or just Join) -> Choose a player and then enter your IP from Radmin VPN:

Send to your teammates your Radmin VPN IP, port (by default it's 7777) and server password if you set it up

Make sure you've done all the steps from the General setup section of this article
Open Terraria, click on Play in the main menu -> Multiplayer -> Join via IP (or just Join) -> Choose a player and then enter host's IP from Radmin VPN. If you don't know it right-click on his nickname in the Radmin VPN network and choose copy IP address
Enter port number - by default it's 7777
If server requires a password - the Host should tell you this one

And you're done! Enjoy the game :)
